Ahhhh, this brought back memories. The week Sputnik was sent to space, our teachers introduced us to this drill. I don't remember exactly how old I was. Eight? Nine?
It created all sorts of problems for the girls as we wore dresses and skirts to school. And boys (being boys) tried to look up our skirts while we were crouched on the floor.
I wonder what things from this era will amuse our descendants. Will they look at our antique cell phones and microwaves and shake their heads in dismay. Didn't they know that stuff will cause cancer?
Life is funny, isn't it?
